NH Pesticide Applicator study guide
NH Pesticide Applicator · Work through your exam, one topic at a time.
The New Hampshire Pesticide Applicator credential is a state certification that allows an individual to buy, mix, load, or apply restricted-use and other regulated pesticides in commercial, agricultural, or other professional settings. Administered through the New Hampshire Department of Agriculture, Markets, and Food - whose pesticide program appears on the department site under both Farms & Businesses and Licenses & Permits - certification signals that the holder can apply pesticides lawfully, safely, and with attention to human health and the environment. The NH Pesticide Applicator study guide has 6 sections and about 2,121 words.
01Pesticide Laws and Regulations: Federal FIFRA and New Hampshire Rules
Federal law (FIFRA) requires every pesticide sold or distributed in the U.S. to be EPA-registered, classifies products as general-use or restricted-use (RUP), and makes it a violation to use a product "in a manner inconsistent with its labeling." In New Hampshire, pesticide regulation is administered by the Division of Pesticide Control within the NH Department of Agriculture, Markets & Food under RSA 430 and the state's administrative rules.

Signal words summarize acute toxicity across all routes. Category I is "DANGER - POISON" (with skull and crossbones) for the most toxic oral, dermal, or inhalation values, or "DANGER" alone for severe eye/skin irritation or corrosivity; Category II is "WARNING"; Categories III and IV are "CAUTION." The word reflects the most severe route, so a product can be relatively safe orally yet still labeled DANGER for skin effects.

Once applied, a pesticide can be adsorbed to soil particles, dissolved in soil water, volatilized to vapor, carried off by runoff or erosion, taken up by plants, or degraded. Adsorption rises with clay content and organic matter, which reduce mobility.
341 words, about 2 min04Pest Identification and Integrated Pest Management
IPM is a decision framework, not a ban on pesticides: identify the pest correctly, monitor and scout, compare the population to a threshold, choose the least-risk effective combination of tactics, then evaluate results. The economic injury level (EIL) is the pest density at which damage equals the cost of control; the action threshold is set at or below the EIL to allow lead time.

Every label carries the brand and common name, active and inert ingredient percentages, EPA registration number, establishment number, formulation abbreviation, signal word, precautionary statements, PPE, first aid, environmental hazards, storage and disposal, and the directions for use: sites, target pests, rates, application methods, restricted-entry interval (REI) and preharvest interval (PHI) . Supplemental and 24(c) SLN labels must be present and followed; they modify, they do not replace, the base label.

Flat-fan nozzles suit broadcast herbicide and fertilizer sprays on booms; even/deflector tips reduce drift near sensitive areas; hollow cones give smaller droplets and better penetration for insecticides and fungicides; full cones cover soil-directed sprays; air-induction tips produce coarse, drift-resistant droplets. Higher pressure and smaller orifices mean smaller droplets and more drift; larger droplets reduce drift but increase runoff potential.
